The increase in both automation and precision in the analysis of geological materials has had significant impact upon forensic investigations in the last 10 years. There is however, a fundamental philosophical difference between forensic and geological enquiry. This paper presents the results of forensic geoscientific investigations of three cases of wildlife crime. Two cases involve the analysis of soils recovered after incidents of illegal badger baiting in the United Kingdom. The third case involves the illegal importation of Eleonora's Falcon (Falco eleonorae) into the United Kingdom from the Mediterranean. All three cases utilise the analysis of soils by a variety of physical, chemical and biological techniques. These involve mineral and grain size analyses, cation and anion compositions, pH, organic content and pollen analysis. The independent analysis undertaken by specialists in each of these three main fields conclude firstly, that there is a significant similarity between sediments taken at the crime site at both badger setts and with sediments recovered from various spades, shovels and clothing belonging to suspects and secondly, that the soils analysed associated with the removal of the falcon eggs in the Mediterranean contained characteristics similar in many respects to the soils of the breeding areas of F. eleonorae on the cliffs of Mallorca. The use of these independent techniques in wildlife crime detection has great potential given the ubiquitous nature of soils and sediments found in association with wildlife sites.  相似文献

Previous research has established a relationship between Contraceptive Self-Efficacy (CSE), as measured by the 18-item CSE scale, and young women's contraceptive behavior (Bilodeau, Forget, and Tetreault, 1994; Heinrich, 1993; Levinson, 1986; Wright, 1992). In this paper, we continue to explore the scale and its relationship to contraceptive behavior with four diverse samples to establish generalizability and to set guidelines for use of the scale. A series of correlational analyses were conducted with each sample. A pattern of low correlations among CSE items across samples emerged, indicating that use of the total item set separately as the basis for CSE was warranted. Zero-order and partial correlations revealed which CSE items were correlated with contraceptive behavior as well as which items explained unique variance in contraceptive behavior for each sample. Regression analyses showed that CSE was significantly predictive of contraceptive behavior for all samples. These results are discussed in terms of scale properties and use in research and clinical settings. Educational implications are formulated as well.  相似文献

Sustainability reporting can be seen as an attempt to bring improved environmental, social, and governance (ESG) practices to mainstream business. However, this movement to mainstream is hampered by the disconnect between financial and ESG information. Both reporting streams use the concept of materiality to shape firms’ disclosure obligations, but the term carries different meanings for different organizations. One sustainability organization, the Sustainability Accounting Standards Board (SASB), has developed reporting standards to merge sustainability and financial information by leveraging the definition of materiality for financial reporting purposes. This use of financial materiality positions the SASB to collide with the Security and Exchange Commission's (SEC) hands‐off attitude to ESG reporting. In the regulatory void left by the SEC's inaction on sustainability reporting, the SASB provides the best route to reconceptualize materiality in line with society's interest in sustainable business.  相似文献

Conceptual History of Adaptation in the UNFCCC Process   总被引:1,自引:0,他引:1  
While adaptation has, in the last 3 years, become the most fashionable item on the climate policy agenda, this was not always so. Since the early 1990s, numerous scientists and policy makers have been making the case that adaptation has been the overlooked cousin of greenhouse gas mitigation. As both are seen to be of equal importance, the lack of policy on adaptation is interpreted as a political strategy by developed countries to avoid admitting liability and the financial consequences of this admission. A tension between those in favour of mitigation over adaptation activities has strongly characterized the discourse on climate change policy. However, a closer look at the history of the concept of adaptation as applied in the United Nations Framework Convention on Climate Change (UNFCCC) process underscores the original intention that the treaty should focus on reducing the source of climate change, rather than on adapting to the changes. Adaptive capacity was considered to be an indicator of the extent to which societies could tolerate changes in climate, and was not seen as a policy objective. As a result of events that have unrolled since the inception of the UNFCCC, needs and perceptions have shifted. Today, there are strong grounds for having adaptation as a policy goal, but it must be recognized that the UNFCCC, and its Kyoto Protocol in particular, are first and foremost about abating greenhouse gas emissions. Thus, adaptation policy may find a more appropriate home beyond the existing climate change regime.  相似文献

The Republic of Ireland has become infamous for its legal stance against abortion, especially since it went as far as stopping, albeit temporarily, a young rape victim from travelling abroad for an abortion in 1992. I argue that one of the rationales behind anti-abortion law is a post-colonial urge to mark Irishness distinctively by constructing it in exclusively 'pro-life' terms. I discuss examples of how Irish colonial experiences have been used to justify the effort to keep Ireland abortion-free, and to resist that effort. Representations of colonial history in the context of Irish abortion law and politics have changed over time and between groups. Such changes indicate a need for post-colonial critique to account for the fragmentation of colonialism as it is displaced, a need which the conceptualization of post-coloniality as a historical object can address.  相似文献

ABSTRACT

The research project ‘Calling the Shots: Women and contemporary film culture in the UK, 2000–2015’ investigates contemporary women's film history through two primary routes: the statistical analyses of the numbers of women in six key above-the-line professions (director, writer, producer, executive producer, cinematographer and editor), and interviews with 50 women in those same roles (by August 2018 we had interviewed 58). This paper focuses specifically on the permutations of the interview process for constructing women's film history in the contemporary period. Taking into consideration the theoretical, methodological and political issues at stake in recording oral histories of working women filmmakers, we contemplate the consequences of collecting and writing history that is still in medias res.  相似文献
